Connection closed before full header was received

[onyas]

Hi I have a dart file named http-example.dart, it has following content.

import 'package:http/http.dart' as http;
main(List arguments) async {
var url = "http://www.meizitu.com/";
var response = await http.get(url);
print(response.body.toString());
}

When I execute it through dart http-example.dart. It failed with following errors.

Unhandled exception:
